I have it on my truck dont use it much, for some reason they are calling it a power adder when I pull in my association.
It will keep your temps cooler: coolant, trans, intake, and exhaust. I have the big spray loop that I spray on the intercooler, When I start to bring boost up I flip the co2 on and dont shut it off untill I park the truck, this helps get the trans and engine temps back down quick.
It is short lived, just like NOS.... It wouldnt be something you could tow with or use in place of water injection.
